Benefits of technology

[0033]An oil-in-oil type cosmetic composition of the present invention has excellent transfer resistance after application, a luster, favorable spreadability during application, and also excellent stability.
[0034]The above, and other objects, features and advantages of the present invention will become apparent from the following description read in conjunction with the accompanying drawings, in which like reference numerals designate the same elements.

Problems solved by technology

Conventional lipstick compositions have presented the problem of indirect smearing that causes a lipstick applied on lips to be transferred onto a site such as a cup upon contact with the lips.
Due to its large content of wax, usability in a liquid state cannot be obtained, and also luster is insufficient.

[0066]Hereinafter, the present invention will be described more specifically with reference to Examples. However, the present invention is not limited to them by any means. In Examples below, amounts formulated mean % by mass, unless otherwise specified.

[0067]In prior to the description of Examples, effect test methods used in the present invention will be described.

[0068](1) Evaluation Test on Usability

[0069]Actual usability test was conducted by ten expert panelists. Evaluation items on usability were spreadability during application, a luster, a moisture feel, the absence of stiffness, and transfer resistance and were sensorily evaluated (scored) on 5 scales according to scoring criteria shown below. Based on the average of the scores, samples were assessed on according to evaluation criteria shown below. Moreover, in Examples 9 to 20, the absence of stickiness and duration were evaluated after 2 hours from application.

Abstract

The present invention provides an oil-in-oil type cosmetic composition that has excellent transfer resistance after application, a luster, favorable spreadability during application, and also excellent stability. The oil-in-oil type cosmetic composition comprises (a) 5 to 80% by mass of non-volatile hydrocarbon oil, (b) 1 to 70% by mass of non-volatile silicone oil, and (c) 0.1 to 10% by mass of dextrin fatty acid ester. Preferably, the non-volatile hydrocarbon oil (a) and the non-volatile silicone oil (b) are formulated at a ratio (mass ratio) of (a)/[(a)+(b)]=0.4 to 0.8.
